In the previous chapter, you learnt how to create a table, add or remove a column, and change the
data type of a column. In this chapter, you will learn how to insert records, update records, and
delete records.

INSERTING RECORDS IN A TABLE

After creating a table, you can insert records into it by using the INSERT command. The syntax to
insert a record into a table is:

INSERT INTO table_name
VALUES ('val_column1', 'val_column2', ... , 'val_columnN');

The values should be in exact order as they were defined in the table.
Let's insert the following records in the Students table created in the previous chapter:

Table-STUDENTS

Student_id First_name Last_name Marks Address
10001 Amit Sharma 450 E-458, Vikas Puri, New Delhi

10002 Divya Kaushik 480 9, Ansari Road, Daryaganj, New Delhi
10003 Aadarsh Kumar 475 22/12, Sarita Vihar, New Delhi

To insert the above records, you can use the following commands:

INSERT INTO Students VALUES (10001, 'Amit', 'Sharma', 450, 'E-458, Vikas
Puri, New Delhi');
INSERT INTO Students VALUES (10002, 'Divya', 'Kaushik', 480, '9, Ansari Road,
Daryaganj, New Delhi');
